IMPROVEMENT IN COM PENSATlNG-JURNALS.

Specification forming part of Letters Patent No. 198,626, datedlDecember 25, 1877 application filed v April 26, 1877.

Figure 1 is a central longitudinal section of my invention. Fig. 2 is a side and end view of conical sleeve or bush. Fig. 3 is an end view of box or hub. Fig. 4 Vis a side View of swivel' complete.

This i invention has relation to swivels, adapted specially for use in connecting the shafts of vehicles to the axle; and it consists in the construction and combination of parts,

. as hereinafter described, the object being to provide for the adjustment of a conical sleeve to take up wear.`

Referring to the accompanying drawings,

'A designates a square 'or angular bolt or shaft, having one en d diminished and threaded to receive a nut, B. C is a box, in which said bolt or shaft turns. of a pulley, or the center or part of any other device where so much friction takes place that the use of mea-ns for compensating for or talc ing up wear is requisite. In some cases the bolt or shaft will be stationary, while the wheel, pulley, or other object rotates.'

E is a shoulder upon the bolt or shaft, which This box' may be the hub impinges upon one end of the hub or box through which the bolt or shaft passes.

The socket or bore of said box or hub is conical or tapering, its diameter dminishin g toward the end against which comes the shoulder E.

F is a sleeve, of corresponding lconical or tapering shape, and fitting said socket or bore snugly, as shown. The bolt or shaft Apasses through said sleeve, which moves vor remains stationary with the shaft.

One end of said sleeve is widened to form a shoulder, f, which impinges upon the end of the hub or box adjacent thereto.

In practice, the draft or end thrust comes on the shaft A, and is transferred to nut B. From this it passes to the conical bust or sleeve. The wear thus comes on iiange` or shoulder f, and lost motion is taken up by turning the nut B, and advancing the cone into the box or hub.

The conical bush F, having an angular bore or central aperture and a shoulder, f, on its longer end in combination with the conical box or hub angular shouldered and threaded shaft A, and'nut B, the several parts beingl constructed and arranged substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 23d day of March, 1877.

GEORGE D. KEMPTON.
